FTIR and dielectric studies of molecular interaction between ethoxyethanol and nitrobenzene

The dielectric study for the hydrogen bonded binary of Ethoxyethanol and nitrobenzene has been carried out over the frequency range of 10 MHz to 20 GHz at 30°C using Time Domain Reflectometry. The static dielectric constant (ε0) and relaxation time (τ) have been obtained. Using these values the excess permittivity (εE), excess inverse relaxation time (1/τ)E and Kirkwood correlation factor (geff) were determined. On the basis of these parameters, intermolecular interaction and dynamics of molecules are predicated. Conformational analysis of the formation of hydrogen bond has been studied using FTIR spectroscopy. The solvent effect on the formation of hydrogen bond equilibria is discussed in terms of specific interaction between the solute and solvent.
